云龙白洋厂银多金属矿区帚状构造带及其控矿作用

BROOMLIKE STRUCTURAL ZONE AND ITS ORE-CONTROLLING IN BAIYANGCHANG SILVER MULTIMETALLIC OREFIELD, YUNLONG

白洋厂矿区以银为主,共生、伴生铜铅锌汞,系滇西首个发现的中型独立银矿床。矿区东部断裂呈弧形弯曲,并作NNW向收敛、SE方向撒开趋势,这些弧形断裂应是一帚状构造。

In Baiyangchang orefield, Ag is the main metallogenetic element. The paragenetic elements are Cu, Pb, Zn and Hg. It is the first middle scale independent Ag deposit discovered in West Yunnan. In the east part of the orefield, the trend of arcual fault is convergent NNW-wards and divergent SE-wards. These arcual faults must be a broomlike structure.
